The problem here is not asking a clear question. There are millions or billions of tools that are no longer being built today. I made one just now as I was writing this post, it will never be built again. Yes it is a cute conclusion, it outlines an interesting social phenomenon. But 'Tools never die' is not correct. Also, Fred's steam engine is no longer built, it was unique, if you show me steam engines, it is not Fred's steam engine.
